' i The supporting member, 13,; is an. inverted U-shapedbi aoket 01". stray iron, haying t he inte' 'lnediate -,p,or tion; ,and the depending arms, 25.f.- liig tl e a ins, 25, area,.,nun1'ber of open-ings,@26 "to Whioln the ar ne, 16, n1aybe secured 111; any of several achusted posh tions wby nieans ofbolts, 2% extending there through, The, ay ns,2 5-,l maybe-slanted mean weirdly-somewhat Leo; as to follow n, aeg'e'n eral ay th res otgcircles deseribed, about thee pointse oft; attachment 1.1 at thee arms, 1-6,,

to the crankarms, 13. They are secured in any suitable position to the tongue frame, as by means ofmachine screws, 28.

It will be seen that the yoke shaped member, B, arovides a very effective means, not only of securing the guard members in vertically adjusted position, but also 111 malntaining them in their correct spaced relation laterally of the cultivator. The lateral position may be adjusted by, bending, the arms apart, which operation is a very quick and simple means of adjustlng the guard members in this direction.

Being a unitary piece, the yoke, B,'needs no additional braces to the cultivator frame to maintain the lateral adjustment of the arms,'25, and the arm, '16, itself serves to brace the arms, 25, against forward and rearward movement.

Referring now to the operation of the device, it willbe understood that the cultivator is ordinarily used between rows of corn stalks, 29, the inner row, C, being cultivated by the plow gangs on either side, and the cultivator wheels, 15, traversing paths which lie very close to the adjacent rows, D, on either side of the row, G.'

In Fig. '1, one of the corn stalks, 29, has been shown bent over, as at 30, across the path of travel of the wheel, 15, on that side. The noseof the guard member, A, is positioned very near to the ground, and will thus be moved under the recliningstalk by the advance of the cultivator, which will be gradually lifted by the upwardly inclined arms, 17, which will ordinarily engage a fallen stalk beyond the middle thereof.

However, should the cultivation be taking place in a field of unusually tall stalks, the engagement of the arm, 1?, alone against the reclining stalk at a point much nearer the base thereofthan the tip, would, in many cases, tend to injure the stalk, due to the weight of that portion extending beyond the arms, 17, tending to bend the stalk over th arm, 17. In sucha situation the arm, 16, will assist the arm, 17, in raising the stalk, and is inclined upwardly at such an angle as to raise the outer end of the stalk more rapidly than the'intermediate portion is raised by the arm, 17. Thus the weight of the stalk is more uniformly taken care of and the stalk is more readily lifted back to proper position.

For a cultivator having unusually large wheels the guard member may be-extended by shifting the point of attachment of the arm, 16, to theportion, 18, of the arm, 17, and, if necessary, the point of attachment of the arm, 16, relative to the arm, 25, of the supporting yoke may also be changed.

Ihe device is very simple and inexpensive in construction and yet provides for universal adjustment and is so designed as to positions.

minimize the danger of stalks being allowed to get under the wheels of the cultivator. Many times stalks grow outside of the true line of their row, and a guard member extending merely on the outside of the wheel might miss the stalk entirely, where the present guard member, its nose being positioned directly in front of the wheel, will not do so.

Some changes maybe made in the construction and arrangement of the parts of my invention without departing from the real spiritand purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1.111. a cultivator wheel guard, to be used with a cultivator having a tongue frame, an axle crank arm, and a wheel carried at the end of said arm, a V-shaped guard member having a long and short arm, means to attach the long arm to said crank arm in position extending forwardly and downwardly, the short arm being sopositioned relative to the long arm that it will then extend upwardly and rearwar'dly at an angle of less inclination than. that of the long arm, and means for supporting the forward portion of the guard membe'rfrom the tongue frame.
